Abstract

The invention discloses a speed reducer provided with an air cooling, oil collecting, lubricating and clearance eliminating structure. The speed reducer comprises a speed reducer shell, a gear transmission mechanism, an air cooling device and an oil collecting device. The air cooling device comprises a draught fan, an air filter and an oil-gas separator. The speed reducer further comprises a first belleville spring used for applying axial thrust to a first bevel gear and a second belleville spring used for applying axial thrust to a fourth bevel gear. The oil collecting device comprises a circular pipe body, a partition board, an oil storage cavity, an oil inlet and an oil outlet. According to the speed reducer, the gears and lubricating oil in the speed reducer shell are cooled through the air cooling device, and thus the problems that due to long-term working of the speed reducer, the temperature of the lubricating oil is increased, and the performance is reduced can be solved; in addition, when the gears are abraded, the belleville springs can automatically push the first bevel gear and the fourth bevel gear to move in the axial direction, and thus a gear fit clearance caused by frictional abrasion is eliminated; furthermore, the lubricating oil is carried into a gear engagement area through the oil collecting device to lubricate the gears, and thus the lubricating and cooling effects on the gears can be improved.

Description

technical field [0001] The invention relates to a speed reduction device, in particular to a speed reducer. Background technique [0002] The reducer is a transmission device used to convert the high-speed low-torque power output by the electric motor or internal combustion engine into low-speed high-torque output. [0003] The reducer is generally composed of the reducer casing and the gear transmission mechanism arranged in the reducer casing. When the reducer is working, the friction between the meshing gears will generate a lot of heat. In the prior art, the reducer generally passes through the reducer casing. Set lubricating oil to lubricate and cool the meshing gears, but the heat dissipation performance of the existing reducer is poor. The reduction will accelerate the wear of the gears, which in turn will shorten the life of the reducer. [0004] During the transmission process of the reducer, its tooth surface is prone to friction and wear. Friction and wear will ...
